A rapid and efficient oxidative deamination of various α-aminophosphonates allows the synthesis of α-ketophosphonates using ZnCr2O7 • 3 H2O under solvent-free conditions at room temperature. This method is also applicable to the rapid and highly selective oxidation of various amines to aldehydes and ketones in very good yields.
